Quick Start Example

Basic Message Box with Metro Theme

C#:

csharp

using Syncfusion.Windows.Forms;

// Set Metro theme globally
MessageBoxAdv.MessageBoxStyle = MessageBoxAdv.Style.Metro;

// Display simple message box
MessageBoxAdv.Show(this, "File saved successfully!", "Success", 
    MessageBoxButtons.OK, MessageBoxIcon.Information);

// Confirmation dialog with Yes/No
DialogResult result = MessageBoxAdv.Show(this, "Save changes?", "File Modified", 
    MessageBoxButtons.YesNo, MessageBoxIcon.Question);

if (result == DialogResult.Yes)
{
    // Save changes
}

VB.NET:

Imports Syncfusion.Windows.Forms

' Set Metro theme globally
MessageBoxAdv.MessageBoxStyle = MessageBoxAdv.Style.Metro

' Display simple message box
MessageBoxAdv.Show(Me, "File saved successfully!", "Success", _
    MessageBoxButtons.OK, MessageBoxIcon.Information)

' Confirmation dialog with Yes/No
Dim result As DialogResult = MessageBoxAdv.Show(Me, "Save changes?", "File Modified", _
    MessageBoxButtons.YesNo, MessageBoxIcon.Question)

If result = DialogResult.Yes Then
    ' Save changes
End If

Common Patterns

Pattern 1: File Save Confirmation Dialog

Scenario: Prompt user to save changes before closing

C#:

csharp

using Syncfusion.Windows.Forms;

// Set Office2016 Colorful theme
MessageBoxAdv.MessageBoxStyle = MessageBoxAdv.Style.Office2016;
MessageBoxAdv.Office2016Theme = Office2016Theme.Colorful;

// Show confirmation with YesNoCancel
DialogResult result = MessageBoxAdv.Show(
    this,
    "Do you want to save changes to Document1.txt?",
    "Unsaved Changes",
    MessageBoxButtons.YesNoCancel,
    MessageBoxIcon.Question
);

switch (result)
{
    case DialogResult.Yes:
        SaveDocument();
        CloseDocument();
        break;
    case DialogResult.No:
        CloseDocument();
        break;
    case DialogResult.Cancel:
        // Do nothing, stay in editor
        break;
}

Pattern 2: Error Message with Custom Icon and Details View

Scenario: Display error with detailed stack trace or log information

C#:

csharp

using Syncfusion.Windows.Forms;
using System.Drawing;

// Load custom error icon
Image customIcon = Image.FromFile("error_icon.png");

// Set theme
MessageBoxAdv.MessageBoxStyle = MessageBoxAdv.Style.Metro;

// Show with details view
MessageBoxAdv.Show(
    this,
    "Failed to connect to database server.",
    "Connection Error",
    MessageBoxButtons.RetryCancel,
    customIcon,
    new Size(48, 48),
    "Error Details:\n" +
    "Server: db.company.com\n" +
    "Port: 1433\n" +
    "Timeout: Connection timeout after 30 seconds\n" +
    "Stack Trace: at System.Data.SqlClient.SqlConnection.Open()"
);

Pattern 3: Localized Message Box (German)

Scenario: Display message box with German button text and messages

C#:

csharp

using Syncfusion.Windows.Forms;
using System.Globalization;

// Implement custom localizer
public class GermanLocalizer : ILocalizationProvider
{
    public string GetLocalizedString(CultureInfo culture, string name, object obj)
    {
        switch (name)
        {
            case ResourceIdentifiers.Yes:
                return "Ja";
            case ResourceIdentifiers.No:
                return "Nein";
            case ResourceIdentifiers.OK:
                return "OK";
            case ResourceIdentifiers.Cancel:
                return "Abbrechen";
            case ResourceIdentifiers.Retry:
                return "Wiederholen";
            case ResourceIdentifiers.Abort:
                return "Abbrechen";
            case ResourceIdentifiers.Ignore:
                return "Ignorieren";
            case ResourceIdentifiers.Details:
                return "Details";
            default:
                return string.Empty;
        }
    }
}

// Initialize localizer before showing message box
LocalizationProvider.Provider = new GermanLocalizer();

// Show localized message box
MessageBoxAdv.MessageBoxStyle = MessageBoxAdv.Style.Office2013;
MessageBoxAdv.Office2013Theme = Office2013Theme.White;

MessageBoxAdv.Show(
    this,
    "Möchten Sie die Änderungen speichern?",
    "Datei geändert",
    MessageBoxButtons.YesNoCancel,
    MessageBoxIcon.Question
);
